Background
The small crescent-shaped Leskov Island lies about 50 km west of the main axis of the South Sandwich Islands, but appears to be comparable in age to volcanoes along the main arc. Leskov Island, only 900 m long and 400 m wide, is bounded by steep cliffs and is the eroded remnant of a small andesitic stratovolcano. Its arcuate, NE-facing escarpment is concave toward Crater Bay, the site of the main eruptive center. The age of Leskov Island is not known. A single Potassium-Argon determination gave an age of 0.5 million years, but fumarolic activity was recorded along the summit ridge in 1911 and 1964 (LeMasurier and Thomson, 1990).---
